Power Suplly
Setthemaincontrolswitchtothe OFFposition,
and confirm that the power supply cord is
connected to a proper AC outlet.
Set either LOW COOL or
HIGH COOL, as required. (

only ).
Main Control Switch
Caution: Ifthe timer isturned of ,waitat least 3
minutes before restarting the operation ( the
timer set to ON or setting hour).
Thermostat Control Switch
Set the thermostat
control at the desired
setting.(ussuallyat 6~7
is recommended setting
position). If the room
temperature is not
satisfactory after a
reasonable amount of
time, turn the control
clockwise to cool the
room more, or anti
clockwise to cool the
room less.
Whenthetermostatcontrolissetto10,moisturemay
freezeontothecoilsandpreventeffectivecooling.If
this happens, turn the main control switch to FAN,
andthethermostatcontrolswitchanticlockwise.This
will quickly defrost the cooling coil and resume
normal cooling.
Vertical Airflow Direction Vane
(Airflow direction adjusment Up-and-Down)
The vertical airflow
direction vane may
be positioned using
tabsto deflect the air
upward, downward,
or straight on.
Vertical Airflow Direction Vane
Horizontal Airflow Direction Vane
(Airflowdirection adjusment Side-to-Side)
The horizontal
airflow direction
vane may be
adjusted by lever to
deflect the air side to
side ( left,right, or
straight).
Recommendation
Usetheairconditionerunderthefollowingconditionsasbelow:
